To @ZZ whom, it' may concern.-

Be it known that I, THOMAS B. TAYLOR@ citizen oll the United States, residngsatBir-V mingham, in the county of Jelerson and State of Alabama, have invented a new and useful Improvement in Journal-Boxes, of which the following isa specification.

Myimprovement relates to sebi-lubricating journal-boxes for truck-ailes, and it is specially adapted for use with mining-cars for ore, coal,- dsc.

The objectof thy-invention is to provide a journal-bok `which may be readily detached and replaced without'removing the wheel and which also shall be thoroughly efficient for lubricating purposes when in place.

Myinvention in all its details will be clearly understood from the following description,

- reference being had to the accompanying drawings, of which- Figure l is an inner end elevation ;4 Fig. 2, a side elevation g' Fig. 3, a bottom plan view, and Fig. l a vertical central longitudinal section of the bei. y

My invention relates to theonstruction of the journal-box intowhich the inner endet` the hub projects and which surrounds the axle and is secured to the truck-timbers..

This journal-box where it receives the hub is providedV with au annular chamber t to receive packing, the function of which is to absorb the oil which gradually leaks from the oil-reservoir through 'the hub. The box is divided horizontally 'into two parts-the upper part A and the lower part B-which t together by means of a rabbet-joint, asv shown at s, toward their inner ends. Immediately adjacent tothe annular chamber t and at each side of the opening for the axle tubular lugsV r lr are provided upon the upper part A and analogous lugs r' r' upon the lower partB, the upper and lower lugs beingy separated from each other by an interval sufficient to receive.

nuts q. The separate parts of the journalbox are secured independentlyto the truck.

timber and are firmly held together when in place by means of two bolts C, threaded toward their lower ends and passing down through the truck-timber and lugs r r', where they receive the nuts q and q'. To assemble the j carnal-box, the upper part place.

.A is rst'put into place .and secured by the vnutsq, after which the lower part B is put intoA place and secured by means of the nutsV Q'- ment, a nut-lock isnecessary, and l have accordingly provided the yfollowing construction: Upon the under side of the part B, between the ylugs r', a devetailed projection ,fp

is provided, and adjacent to it, in line with 6o its center, is a rib o, provided with a transverse notch'n. D is a Vrectangular metal block having upon its inner side a dovetailedV recess fm., fitting the dovetailed projection p,

vand of such length asrto enter snugly between lthe nuts q'when the latter are properly in Projecting from the center of this block in line with the rib o is a lug l, provided on its inner face with a notch n' in such position as to coincide with the notch n when 7o the block D is in place between the nuts.' To secure the block D in place, a wire l.; of suitable gage is passed through the opening formed by the notches a and n'and' twisted or doubled' upon itself 0n the under side of 75 the lug Z. "When it is desiredto remove the journalfbox in whole or in part for any purv pose, the wire k is untwisted and drawn out and the nut-lockD removed. This permits the nuts q to be unscrewed and the part B of 8o the journal-bonte fall. Next, if it isdesired to remove the upper part Aalso the truck is raised from theaxle by means of-a liftingjack and the nuts q removed, whereupon the upper part'A of the journal-box falls. In this 85 way itwill be seen that the journal-box may be repacked orV repaired or wholly replaced by another without removing the wheel from theaXle.

In addition to the advantages mentioned 9o the journal-boxdescribed is simple and cheap in the matter ot' construction, the upper and lower halves being plain castings requiring no cores and no drilling. In operation the packing is placed drywithin the chamber i,

To lsecure `the nuts o against displace- 55 ivided horizontallyinto me of the opening for the axle, and separated from each other in the region of the bolt-holes for the reception of nuts,in combination with' bolts C of such length as to extend through the truck-timber and below the lugs of the lower section of the journal-box when the parts are assembled, and having their lower portions serew-threaded, nuts q iitting the screw-threaded portions of the bolts for securing the upper section of the journal-box in` place, and corresponding nuts q for securing the lower section of the journal-box in place, substantially as described.

2. A journal-box divided horizontally into two parts provided at opposite sides of the opening for the axle with vertical bolt-holes, said parts in the region of the bolt-holes be-' ing separated from each other for the recep tionv of screw-nuts, whereby the parts may be secured together and independently to the truck by means of bolts C and nuts qand q',

in combination with a nut-lock attachment for preventing the displacement of the nuts lq, substantially as described.

3. In a journal-box having an annular packing-chamber 1f and divided horizontally into two parts, A and B, the tubular lugs r upon the upper part A on opposite sides of the opening for the axle, and eorrespond- THOMAS B. TAYLOR.
